Application filed March 28, 1927. Serial No. fleece. I

This invention relates to improvement in extractor mechanisms forbolt-action firearms and has for its object the production of a simple,reliable and rugged mechanism 5 of theclass described.

'A, further object of this invention is to provide an extractormechanism which may be readily installed and removed from the firearm.

1O lVith these objects in view, my invention consists inan extractormechanism for boltaction firearms characterized by an extractor-barprovided near its rear end with a laterally-projecting locking-lug; abolt provided with a longitudinal chamber for the reception of theextractor-bar and with a laterally-extending passage intersecting thesaid chamber for the reception of the said locking-lug; and a springfornormally holding the said locking-lug in the said locking-passage.

My invention further consists in an extractor mechanism for bolt-actionfirearms characterized as above and having certain other details ofconstruction and combinations of parts as will be hereinafter describedand particularly recited in the claims.

In the accompanying drawings:

Fig. 1 is a broken View in side elevation of the forward end of a boltprovided with my improved extractor mechanism;

Fig. 2 is a View thereof in front end elevation;

Fig. 3 is a transverse sectional view on the line 3-3 of Fig. 1; v

Fig. 4 is a top or plan view of one of the extractor-bars Fig. 5 is aview thereof in side elevation;

and i Fig. 6 is an enlarged broken view in horizontal section showingthe bolt, receiver,

and gun-barrel of a firearm provided with an extractor mechanismembodying my invention.

In the embodiment of my invention herein shown, I employ a pair ofsubstantiallycylindrical corresponding complementary extractor-bars 10having their forward ends beveled as at 11 and each provided upon itsinner face with a notch 12 for engaging the rim 13 of a cartridge 14,which, as usual, is

located in the bore 15 of the gun-barrel 16.

As is the ordinary practice, the gun-barrel 16 is threaded into theinternally-threaded forward end of the receiver 17, as shown in Fig. 6.i Y The inner face of each extractor-bar is cut .away to form aclearance-notch 18 which provides a flat'bearing surface for a. helicalspring 19. The rear end of the outer face of, each of theyextractor-bars is also formed with a notch 20 which results in theformation of a fulcrum-shoulder 21, the function of which willhereinafter appear, and also provides a flat seat for alaterallyprojecting locking-lug 22 which is provided with ashort shank23 projecting through a lateral bore 24 in the rear end of eachextractor-bar where it is riveted over as at 25, so that the locking-lugvirtually becomes a part of the extractor-bar to which it is attached.

The bolt 26 is of the ordinary type and, as shown, is provided onopposite sides of. its vertical center with two longitudinallyarranged.extractor-chambers 27 and 28, the outer wall of-each of which isintersected at its rear end by a locking-passage 29, while the innerwall thereof is intersected by a transversely-arranged spring-chamber 30extending between the said extractorchambers and arranged in line withthe locking-passages 29 aforesaid.

In assembling the extractor-bars 10 in the bolt 26, I first insert oneof'themfthrough the front end of either one of the extractorchambers 27or 28 until its locking-lug 22 is in line with'one of the.locking-passages 29. The spring 19 is now. inserted into thespring-chamber 30 through the opposite locking passage 29 and compressedby' a suitable tool, after which the complemen tary extractor-bar isinserted rearward through the forward end of the oppositeextractor-chamber until its locking-lug 22 is in line with thelocking-passage 29 of the chamber in question.

As thus installed, the single spring 19 serves to hold the locking-lugs22 of the respective extractor-bars in the respective locl ing-passages29 and permits the outer ends of the respective extractor-bars to swingoutward upon their fulcrum-shoulders 21, as may be required to permitthe notches 12 to be engaged with and disengaged from the rim 13 of thecartridge 14.

Should it be necessary for any reason whatever to remove theextractor-bars from the bolt, it is only necessary to force one of thelocking-lugs 22 inward to clear it from its locking-passage'29 and then.draw the extractor-bar, of which it forms a part,'f0rward and outthrough the open forward end of the particular extractor-chamber in;which.

the extractor-bar is housed. The removal of this extraetor-baras justdescribed-will permit the spring 19 to beremoved laterally outwardthrough the lockingpassage'29' just vacated, after which the remainingioeking-bar may be readily removed by disengaging its locking-lug fromits adjacent locking-passage 29 and in turn drawingiit outward throughtheforward end of the other longitudinal extractor-chamber.

I claim: Y

1. The combination with theibolt' of a bolt-action firearm; of twolongitudinallyextendinge extractor-chambers respectively formed onthe-opposite sides of the center of the said bolt ;a transverselocking-passage intersecting each of; the said extractor chambers nearthe rear ends thereof; two.

extractor-bars housed in the said extractor: chambers respectively withcapacity for rocking-movement; a transversely-ofisetting locking-luglocated near the rear end of each of the said extractor-bars; and aspring'impinging at its opposite ends against the said extractor-barsrespectively for yieldingly holding the said locking-lugs. in the saidlocking-passages.

2; The combination with the bolt of a bolt-action firearm; of twolongitudinallyextending extractor-chambers respectively formedfon theopposite sides of the'center of the said' bolt a transverselocking-passage intersecting eachqotthe said extractor,- chambers nearthe rear endi thereof; a spring-chamber formed in the said bolt'in linewith the said locking-passages; two "extractor-bars housed in the saidextractorchambers respectively," with capacityv for rocking movement; atransversely-oflsettingi locking-lug nearv the rear end of 'each of thesaid eXt-ractor=bars; a spring-chamber formed in the said bolt in linewith the said:

7 specification.

lockingpassages; and a spring located in the said spring-chamber andadapted to impinge at its oppositerends against the said extractor-barsfor holding the said lockinglugs in.the said locking-passages.

3. The combination with the bolt of a bolteaction firearm; of twolongitudinall extending extractor chambers respective y formed on theopposite sides of the center of the said bolt; a transverselocking-passage intersecting each of the said extractor-cham- I bersnear the rear ends thereof; two ex tractor b arshoused in the saidextractorchambers respectively with capacity for rock] ng movement a atransversely-offsetting locking-lug locatednear the rear end of each ofthe said extractor-bars; and a spring impinging at'itsopfulcrum-shoulder formed upon each of the said extractor-bars;

posite ends against the said extractor-bars respectively foryieldingly'holding the said located near the rear end of 'each'of thesaid extractor-bars; and a spring located 'inthe aforesaidspring-chamber and impinging at its opposite ends against the saidextractorbars respectively for'yieldingly holding: the

said locking-lugs in the said locking pasi sages.

In testimony whereof, I have signed'this LovELL HPAGE? I
